The Office Boy

A boy mouse works in an office and flirts with the secretary, a girl mouse. The big boss tries to chat up the secretary, too, but the office boy shows the boss's wife into the office. The office boy is happily reunited with the secretary, while the boss gets beaten up by his wife. The office boy and the secretary ride away from the office on a train, singing a patter-style love song together.

Office Boy, Secretary, Boss, Boss's Wife

The boy and girl mouse looked so much like Mickey and Minnie that Disney made Van Beuren Studios curtail these characters in the early 1930s. They returned as Oscar and Daisy.
